Remarks

xlPrecision results are returned
as text that look like numbers, not as values that Excel recognizes as
numbers. This is because Excel would truncate the results to 15 significant
digits if it recognized them as numbers.

format_negative,
format_thousands, format_currency, and exponential_notation are all ignored by
the 25 SD edition of xlPrecision.

format_thousands and
exponential_notation are ignored by the 35 SD edition of xlPrecision.

num can accept
both numbers and text.

num can accept
text formatted with the local currency symbol and thousands separators, and
negatives can be formatted with either a leading hyphen or parentheses.

num can accept text up to 32,767
characters long.

You can use the results of
xlPrecision functions as the operands in other xlPrecision formulas without
losing any precision, but using them as operands in Excel's arithmetic
functions will truncate them to 15 significant digits.

Decimal symbols, thousands
separators, and currency symbols are all localized. This means that an
xlPrecision formula that returns "$1,234,567.89" in the USA will return
"1.234.567,89 €" in Germany, "1 234 567,89 €" in France, "1 234 567.89 kr" in
Estonia, and "1.234.567,89Lek" in Albania.

The 32,767 SD edition can only
provide a maximum of 32,767 total characters, including all formatting
characters such as decimal, leading hyphen or parentheses for negatives, and
thousands separators. As a result, it can only return the maximum 32,767
significant digits when the result is an unformatted positive integer.
This is due to Excel's limitation of 32,767 characters in a cell. In all
cases, the 32,767 SD edition will give you as many significant digits as
possible with the formatting you have chosen.

Depending on how many significant
digits the edition of xlPrecision provides, the result may be too long to
conveniently view. You can view the full result by right-clicking the cell and
choosing Format Cells | Alignment | Wrap Text, and widening the column to the
width of the screen. An easy way to view the full result without changing
column widths or wrapping text is to right-click the cell, choose Copy, and
then paste into Notepad or a
word processor.
